Description: length: ca. 10.5; length of fore-body: 4.2; length of head: 1.85; breadth of head: 1.5; length of antennae: 3.1; length of pronotum: 1.58; breadth of pronotum: 1.2; length of elytron: 1.28; breadth of elytra: 1.43. Body black, palpi, antennae and legs testaceous. Head and pronotum shiny but clearly, densely micro-reticulate, abdominal tergites entirely covered with strong transverse micro-striae. Pubescence sparse, short and erect on fore-body, denser, long and decumbent on abdomen. Habitus: similar to Fig. 4h.

Male: abdominal sternite VIII: Fig. 5s8; aedoeagus: Fig. 5arl; Plate AEB.

Female: abdominal sternite IX: Fig. 5vp.

In colour, habitus and puncturation this species is indistinguishable from O. novacaledonicus , but differs in its averagely lesser size, stronger microsculpture both of the head and pronotum and of the abdomen, as well as in the primary sexual characters.
